Dual MC33926 Motor Driver Carrier

This dual brushed DC motor driver, based on Freescale’s MC33926 full H-bridge, has a wide operating range of 5 – 28 V and can deliver almost 3 A continuously (5 A peak) to each of its two motor channels. The MC33926 works with 3 – 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM, and features current feedback, under-voltage protection, over-current protection, and over-temperature protection.
